Students should be given the following links of videos to view prior to the lesson. These videos show how to set up a titration, how to do a titration and the last video is a general overview of titrations.
Students should be given the following handout reviewing what they learned from watching the above videos. The teacher should also review how to solve titration problems (essentially stoichiometry problems). See the following handout.
Students will determine the concentration of acetic acid in vinegar in this lab. Below is the pre-lab which should be given to students the lesson prior to the lab to complete. A copy of this lab is also included below (this can probably be found in any grade 11 chemistry textbook).
Curriculum Expectations: 2.1 Use appropriate terminology related to aqueous solutions and solubility 2.6 Use stoichiometry to solve problems involving solutions and solubility 2.7 Determine the concentration of an acid or a base in a solution using the acid-base titration technique
